09-43-04 In this anterior superior view of a heart with repaired tetralogy of Fallot, the pulmonary conduit has been retracted forward to show the anterior interventricular coronary artery (anterior descending coronary artery) arising from the proximal right coronary artery and coursing across the right ventricular outflow tract. Note the sutures depressing the pate of the anterior interventricular artery as it takes its normal path along the interventricular septum. The circumflex artery (not seen) arises from its own orifice from the left-facing sinus and extends in the normal fashion along the left atrioventricular groove.
